The retractile properties of the Koiled Kords gives the user a greater range of motion needed in demanding environments. Whitney Blake's light, medium, and heavy-duty Koiled Kords are manufactured using a highly-mobile and extremely durable Neoprene jacket. The cords have an extension length of 10-to-20 feet (2-to-4 feet retracted) and are available in 12AWG through 18AWG.
